Description

The present invention relates to a medical device, and more particularly to a catheter cleaning joint structure used for a sputum suction tube.

As shown in FIG. 1, in a catheter cleaning joint 1a used for a conventional sputum suction tube (not shown), the catheter cleaning joint 1a includes a tube body 10a and a tube joint 11a installed on one end of the tube body 10a. On the pipe joint 11a, a connection port 110a communicating with the inside of the pipe body 10a is installed.
The tube body 10a opposite end is connected to the soot suction pipe, and in the pipe body 10a, a check valve (not shown) that contacts the connection port 110a is installed, and the dirt in the soot suction pipe flows back, It is possible to prevent leakage from the connection port 110a.
However, a liquid such as a medicine can be injected from the connection port 110a, and the inside of the suction tube can be cleaned or disinfected.
When trying to inject a medicine, an appropriate amount of medicine is sucked by an injector such as a syringe, and then the medicine is inserted into the connection port 110a and injected into the sputum suction tube by the catheter cleaning joint 1a.

However, in the conventional catheter cleaning joint 1a, only a certain caliber size injector (not shown) can be inserted into the connection port 110a.
Since the diameter of the connection port 110a is 3.85 mm to 3.90 mm, other injectors having a larger diameter cannot be used, which is a limitation in use.
At the same time, the general catheter cleaning joint 1a is compatible with commercially available injectors and the size specification cannot be changed as needed.
The present invention has been made in view of the above-described drawbacks of a catheter cleaning joint structure used in a conventional sputum suction tube.

The catheter cleaning joint structure used for the suction tube of the present invention is connected to a combination of two types of caliber injectors 2 and 3 (see FIGS. 6 and 8), so that the catheter cleaning joint 1 can be installed in an injector. Can be expanded

The catheter cleaning joint 1 includes a tube main body 10 and a tube joint 11.

The inside of the tube body 10 has a hollow shape and includes a catheter connection end 100 and a connection port end 101.

The catheter connection end 100 and the connection port end 101 are installed in a state of being separated from each other, and both communicate with the inside of the tube main body 10, and a check valve 12 is installed in the tube main body 10. .

In addition, the catheter connecting end 100 of the tube body 10 is connected to the catheter 13, and the catheter cleaning joint 1 is further connected to a sputum suction tube (not shown).

The pipe joint 11 is fitted and installed on the connection port end 101 of the pipe body 10, and the pipe joint 11 is provided with a connection port portion 110 having a stepped shape (that is, having a smaller outer diameter). In the connection port portion 110, a connection port 111 is formed.

When the pipe joint 11 is fitted and installed on the connection port end 101, the connection port 111 communicates with the inside of the tube body 10, and thus the check valve 12 is connected to the connection port from the inside of the tube body 10. It is pushed up with elasticity at 111 (see FIG. 4).

In the embodiment of the present invention, the check valve 12 is pushed up at the connection port 111 by the elastic part 120, so that the elastic part 120 provides elasticity, and thus the check valve 12 is not subjected to external force, Normally, the connection port 111 is closed.

Further, a lid 112 is further installed on the connection port 110 of the pipe joint 11 and is connected to the pipe joint 11 by the lid 112 flexible belt 113.

When the catheter cleaning joint 1 is not used, the flexible belt 113 is bent, and the connection port portion 110 is covered with the lid 112 to close the connection port 111.

With the composition of the structure described above, a catheter cleaning joint structure used in the present invention soot suction tube can be configured.

5 and 6 are schematic views showing a state in which the injector 2 having a certain diameter and the above-described catheter cleaning joint 1 correspond to each other.

The diameter d of the connection port 111 of the catheter cleaning joint 1 is in the range of 3.85 mm to 3.90 mm, and an injection port 20 is provided at the end of the injector 2.

Since the diameter d 'of the injection port 20 corresponds exactly to the diameter d of the connection port 111, the check valve 12 is pushed after the injection port 20 of the injector 2 is inserted.

In this way, the connection port 111 is opened so as to communicate with the inside of the tube body 10, and thus the medicine in the injector 2 can be sent to the sputum suction tube (not shown) by the catheter cleaning joint 1.

Further, FIGS. 7 and 8 are schematic views showing how the injector 3 having another diameter and the catheter cleaning joint 1 correspond to each other.

The connection port portion 110 of the catheter cleaning joint 1 has a stepped design, and the outer diameter D of the connection port portion 110 is in the range of 6.5 mm to 7 mm, so that an injector 3 having another diameter can be inserted. An injection port 30 is provided at the end of the injector 3.

Since the diameter D ′ of the injection port 30 corresponds to the outer diameter D of the connection port part 110, after inserting the injection port 30 of the injector 3, the check valve 12 is pushed, and thus the connection port 111 is opened. The pipe body 10 can be communicated with the inside.

Similarly, the medicine in the injector 3 can be sent to the sputum suction tube (not shown) by the catheter cleaning joint 1.

Therefore, the catheter cleaning joint structure used for the present suction tube can be connected in combination with two types of syringes 2 and 3 so that the injectors 2 and 3 can be connected to the catheter cleaning joint 1 for installation. The range can be expanded and thus is not limited to the use of single caliber injectors, and is not tied to existing size standards, and existing injectors can be used.

The names and contents of the present invention described above are only used for explaining the technical contents of the present invention, and do not limit the present invention. Equivalent applications based on the spirit of the present invention, conversion of parts (structure), replacement, increase / decrease in quantity are all included in the protection scope of the present invention.

  The present invention has the novelty that is a requirement for utility model registration, has sufficient progress compared to similar products of the past, has high practicality, meets the needs of society, and has a very high industrial utility value. large.
